SPECIFICATION forming part of LettersvPatent N o. 473,625, dated April26, 1892.

Application filed July 14, 1891.

To a/Z whom it may concern:

' Be it known that I, WILLIAM TURNER GREGG, a citizen of the UnitedStates, residing at Lakeport, in the county of Lake and State ofCalifornia, have invented a new and useful Door, of which the followingis a specication.

This invention relates to doors; and the object of the same is to renderthe door con- ,vertible from its usual paneled construction into aglass, blind, or screen door.

To this end the invention consists in the construction hereinafter morefully described and claimed, and as illustrated on the accompanyingsheet of drawings, wherein- Figure l is a perspective view of thisimproved door, showing panels in its upper portion and a wire screen inits lower portion. Fig. 2 is a similar view showing'slats in the upperportion anda glass panel removed from the lower portion and turned so asto exhibit the edge of the panel. Fig. 3 is 'a horizontal section on theline 3 3 of Fig. l. Fig. 4 is a vertical section on the line 4 el. ofFig. 2.

Referring to the said drawings, the letters T, M, and B designate,respectively, the top, middle, and bottom rails of a door-frame, whichare connected at their ends with the hangingstile H and the lock-stileL, as is usual in the construction of doors, and above and below saidmiddle rail are openings wherein the panels are usually inserted.Heretofore provision has been made for removing said panels andsubstituting therefor screens or blinds, securing the same removably inplace by various means; and th? present invention contemplates theprovision of securing means for this purpose which cannot be manipulatedto remove the panel, window, screen, or blind sections when the door isclosed. At the sides of the said openings in the door-frame are verticalbeads V, standing flush with the outer face of the frame. In bothhorizontal edges of each opening are grooves G.

R is a recess in the hanging-stile at the end of the groove G in eachedge of the middle rail, and O are openings through the lockingstileopposite the other ends of these grooves, a cavity C being formed in theouter edge of said locking-stile j ust below each opening O.

The various sections which are adapted to be secured detachably in theopenings in the Serial No. 399,482. (No model.)

door-'frame may be of glass, netting, panels, or stationary or movableslats, and they may be in one panel or more, in which latter case themuntin U is removable with the` section, there being but two sections,as shown, one above and the other below the middle rail M. lf thesection contains panels P, it will have no frame; but if it containsanything else it will be provided with a frame F. This frame (or thesides of a paneled section) is of the following construct-ion: Itsvertical edges are cut away, as at A, so that when it is inserted in thedoor-frame the angles formed at these cutaway edges will strike thevertical beads V on the hanging and locking Stiles, as seen in Fig. 3. j`At the lower edge of the frame is a depending tongue D, which fits thegroove G in the bottom rail B, or this tongue D projects upwardly fromthe upper edge of the panel or section at the upper portion of the doorand passes into the groove G in the top rail T. The other horizontaledge of the sectionthat is, the edge adjacent the middle rail Misprovided with a groove G registering with that in the middle rail whenthe section is in place.

S is a locking bar or strip of rectangular cross-section, ot' asizeadapted to pass through the opening O and to fit in the registeringgrooves G and G', and of such length that when its tip rests in therecess R in the hanging-stile its outer end will be flush with the outeredge ot' the locking-stile. To the outer end of this strip is hinged aneye or ring shaped handle I, which normally falls and stands in thecavity C.

To insert a section in this door-frame, the tongue D is inserted in thegroove in the top or bottom rail, the grooved edge of the section thenborne toward the door until its cut- IOO Of course the form and size ofparts j tongues faced with metal or changed to a considerable extentwithout departing from the spirit ofthe invention. Another form ofhandle could be used than that lettered l; but with the constructiondescribed the ringhangs nicely in the cavity and may be swung outwardlyto put the iinger through when it is desired to draw the locking-strip.The latter might be of other cross-section than that shown, and mighteven he of metal, or the two horizontally-arranged panels in a sectionmight be independent of each other and locked by two locking-strips ofhalt the length ofthe one shown and inserted through both edges of thedoor until their ends met at the center. However, I prefer theconstruction shown, because it. absolutely prevents the lateraldisplacement of the locking-strip, as both its ends are held fromlateral movement in every direction.

A door of this kind can be cheaply constructed and will be veryserviceable in a dwelling-house, and by a slight change in the structurethe ordinary doors now in use could be converted into the form of doorshown. In winter the paneledl-or the glass section is inserted and inwarmer weather the netting or the blind section, and in event of asudden change of weather the sections could be replaced by others in afew minutes.

With the exceptions above noted the door is the same as those nowmanufactured, andv its style, proportions, and configuration may ofcourse be such as is desired and as conforms with the architecture ofthe building in which the door is employed.

It desired, the opening O and cavity Cmay ,be duplicated in thehanging-stile and the recess R omitted,.in which case the strip could bewithdrawn from either edge of the door and the latter could be hinged ateither edge.

Vhat is claimed as new is- 1. The combination, with a door-frame havingan upper and a lower opening, the vertical sides of each opening beingprovided with beads flush withV one face of the door and the horizontalsides of each opening being provided with grooves, that in the middlerail opening through the locking-stile of the doorframe, of paneled,glass, screen, and blind sections interchangeably fitting said openings,each section being cut away at its vertical edges, so as to engage saidbeads, having a groove in one edge adapted to register with that in themiddle rail and having a tongue on its other edge adapted to tit thegroove at the other vertical side of said opening, and a locking-stripremovably inserted through the locking-stile and standing in saidregistering grooves, as and for the purpose set forth.

2. The combination, with a door-frame having an upper and a loweropening, the horizontal sides of each opening being provided withgrooves, that in the middle rail extending through the locking-stile ofthe doorframe, of paneled, glass, screen, and blind sectionsinterchangeably fitting said openings, each section having a groove inone edge adapted to register with that in the middle rail and a tongueon its other edge adapted to itthe groove at the opposite side of saidopening', and a locking strip re n1ovably inserted through thelocking-stile and standing in said registering grooves, as and for thepurpose set forth.

The combination, with a door-frame having an upper and a lower opening,the horizontal sides of each opening being provided with grooves, oneend ot' the groove in the middle rail being continued into a recess inthe hanging-stile and the other end being continued in an openingthrough the lockingstile, of paneled, glass, screen, and blindi sectionsinterchangeably iitting said openings, each sectionhaving a groove inone edge adapted to register with that in the middle rail and a tongueon its other edge adapted to tit lthe groove at the opposite side ofsaid opening, and a locking strip removably inserted through thelocking-stile, its body standmg in said registering grooves and itsinner end -in said recess, as and for the purpose set forth.

4. The combination, with a door-frame having an opening, the horizontalsides of such opening being provided with grooves, one of which extendsthrough one of the stiles of the door-frame, of paneled, glass, screen,and blind sections interchangeably iitting said opening, `eachsectionhaving a groove in one edge adapted to register with saidextended groove and a tongue on its other edge adapted to nt theopposite groove, a locking-strip removably 1nserted through said stileand standing in said registering grooves, and ahandle at the outer endof said strip normally flush with the edge of said stile, as and for thepurpose set forth.

5. The combination, with a door-frame having an opening, one horizontalside of such opening being provided with a groove which is continuedthrough one of the Stiles in the door-frame in an opening having acavity around its outer end, of paneled, glass, screen, and blindsections interchangeablytting said openings, each section having agroove in one edge adapted to register with that in the frame,detachable connections between its other edge and the opposite side otthe opening, a locking-strip removably inserted through said stile, withits body standing in said registering grooves, and a handle connected tothe outer end of said strip and normally standing in said cavity flushwith the outer edge ot' said stile, as and for the purpose set forth.

6. The combination, with a door-frame having an upper and a loweropening, the horizontal sides of each opening being provided withgrooves, one end of the groove in the middle rail being continued into arecess in one stile and the other end being continued through theopposite stile in an opening having a cavity around its outer end, ofpaneled, glass, screen, and blind sections interchange- IOO tog
